近些年来,随着塑料工业的持续高速发展,塑料包装得到了广泛的应用。但由于塑料包装废弃物的日益增多,"白色污染"问题已对生态环境造成了严重影响。因此,在使用和对塑料包装材料进行生态设计时,用性能价格比更好的材料,用更符合时代特征的技术与方法进行可降解塑料的开发,加大对塑料废弃物的回收再利用,已成为当务之急。目前,塑料包装材料废弃物的回收处理方法有很多种,本文对其主要方法作一探讨。 相似文献

New regulations require improvement of plastic packaging waste management to meet higher recycling rates. One solution for today's multilayers and other sorting challenges is tracer-based-sorting (TBS). TBS uses fluorescent tracers to provide sorting information on packagings. Industrial printing tests with tracer materials showed good printing quality. For TBS waste management feasibility studies, extensive packaging sorting plant input analyses were carried out, focusing on materials, color, label type, and label whereabouts. Sorting tests on a TBS-modified NIR-sorter resulted in excellent detection rates. LCA showed the reduced climate impact of TBS compared to conventional sorting technology. Implementation and transfer of TBS to other industries show high potential. 相似文献

In this work, results are presented on the application of the dissolution/reprecipitation technique in the recycling of polymers
from waste plastic packaging materials used in food, pharmaceuticals and detergents. Initially, the type of polymer in each
packaging was identified using FT-IR. Furthermore, experimental conditions of the recycling process (including type of solvent/non-solvent,
initial polymer concentration and dissolution temperature) were optimized using model polymers. The dissolution/reprecipitation
technique was applied in the recycling of a number of plastic materials based on polyethylene (LDPE and HDPE), polypropylene,
polystyrene, poly(ethylene terephthalate) and poly(vinyl chloride). The recovery of the polymer was measured and possible
structural changes during the recycling procedure were assessed by FT-IR spectroscopy. Potential recycling-based degradation
of the polymer was further investigated by measuring the thermal properties (melting point, crystallinity and glass transition
temperature), of the polymer before and after recycling, using DSC, their molecular properties (average molecular weight)
using viscosimetry, as well as their mechanical tensile properties. High recoveries were recorded in most samples with the
properties of the recycled grades not substantially different from the original materials. However, a slight degradation was
observed in a few samples. It seems that this method could be beneficial in waste packaging recycling program. 相似文献
